I love Keyboard Maestro and use it constantly.
I have a KM smart folder that shows macros used in the last 12 hours. It is most useful to view this folder sorted by Date Used, so that they appear in order of use.
Other folders are more categorical– Usually centering around an app. I find it most useful to view these sorted alphabetically, so I can find whichever macro I'm looking for, and it will always be in the same place.
Another example would be– The Sort Macros By Use Count option would be more useful if it could be assigned to an individual smart folder.
That being said, as lazy as it makes me sound, switching a global Sort Macros As menu item when switching from viewing one folder to another is just cumbersome enough that I generally don't bother.
Just a thought!
Loving the new updates.
